DescriptionOption
The IP defragmentation preprocessor uses memory management
routines that are used in other parts of Snort. It uses the default memory
limit of 4194304 bytes (4 MB) and a timeout period of 60 seconds. The
timeout period is used to determine a length of time that a unassembled
fragment should be discarded.
Perform IP defragmentation
Normalizes rpc multiple fragmented records into a single unfragmented
record. It does this by normalizing the packet into the packet buffer. if
stream4 is enabled, it will only process client side traffic. It defaults to
running on ports 111 and 32771I.
Perform RPC Traffic
Allows Snort to normalize Telnet control protocol characters from the
session data. It accepts a list of ports to run on as arguments. Also, it
normalizes into a separate data buffer from the packet itself so that the
raw data may be logged or examined with the raw bytes content.
